IMPRQVED APPARATUS POR CDOLIG-'BEER AND OTHER LIQUIDS.

The Schedule referred ilo-,in these Lettere Patent and making part ofthe same T o all 'whom it may concern:

Be it known that I, THEoboRn GRNDMANN, of

Cleveland, in the county of Cuyahoga, and State of Ohio, have inventedanew and improved. Cooling-Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing hadto theaccompanying drawings forming part of this 'specicatiomin which- Figure lrepresen'ts a sectional elevation of my im- .provedcooling-apparatus.'

' l. Figure 2 is a plan or top view of the same.

Similar letters of reference indicate corresponding gparts; l

- This invention relates to a new apparatus for cooling mash-beer andotherliquids, and consists in a novel arrangement-,of "pipes, passages,andvessels for obtaining the `desired result, namely, the rapid andthorough coolingof the liquid, `and the4 absolute discharge of thewarmed cooling-liquid.l

The cooling-vessel A`is made of serpentine form, as shown in iig.' 2,itforming a narrow vertical channel, open on top or closed, and adapted toreceive at one end the liquid which is to be' cooled,.near the top,through al pipe, a,'and to discharge it near the bot` tom, at the otherend, through a pipe, b.

y This serpentine vessel A is placed into a vessel, B, which is'ofcylindrical or other suitable form, and which is somewhat higher than A,so that the latter may be raised above the bottom of B, on' legs orsupports c,

` `as shown. y

A vertical A,pipe-,0, having horizontal branches dell or arose at-itslower end, is placed into the vessel B,

l `and has a funnel, e, at its upper end.

, l Witnesses:

i The cooling-liquid, such as water o'r other substance, is poured intothe funnel, and is in the pipe C conducted to the bottom of lthe vesselB, where it is spread by the branches d. The warm cooling-liquid arisesto the top, and flows out through a pipe, f.

Small pipes g g are itted through the serpentine vessel, to facilitatethe circulation of the cooling-liquid. The mash or beer, as it passesthrough the vessel A, is thoroughly cooled, and the cooling-liquid, asit gets warm, is discharged. l

Having thus described my invention, n I claim as new and desire tosecure by Letters Patent- 1. The arrangement in a cooling-chamber, B, ofa serpentine vessel A, raised above the bottom of said chamber, andsurrounded by the cooling-fluid on every side, as shown and described.

2. The improved serpentine vesselA, having an inlet-pipe, a, at Vthe topof chamber' B, and an outletpipe, b, at the bottom thereof,to allow thewarm liquid to flow through the cooling-fluid, and be de prived of itscalorie, in the manner described.

3. The combination of a surrounding chamber, B, having induction-pipe Cin the center, and the eduction-pipe f on the rim thereof, to admit of aconstant ow and change ofthe cooling-fluid, with a vessel, A, pv*through whichV the liquid to be cooled ows, in the manner set forth,each of said vessels being constructed and arranged in respect to theother, as and for the purpose specied. m
